I think there's a lot more involved than just replacing the key. As I understand it the new key and your car must be "mated." The dealer must set the key code and I believe reset all of your car codes for it to work, and that is probably a pricey process.

This is not correct... the key comes shipped pre-programmed to work with your car... no resetting of any codes in the car... you get the key and plug it in and you are set to go... sometimes the kay can be shipped to you directly not to the dealer... your car comes with a set number of key designations... up to 8... so slots 1&2 are accounted for from the factory... when you order a new key that takes slot 3 and the car is ready for slots 3-8 to be filled.

Think in the way of an RSA VPN Key... rolling code constantly, but the VPN always knows what code should be showing at any given time you log in.
